2020 Demographic and Housing Characteristics (DHC)
2020 Demographic and Housing Characteristics (DHC) – the old Summary File (SF1) – is a complete (100 %) count of all Americans and has variables such as age breakouts (including single year ages at the tract level and above), race and race by Hispanic origin and housing variables like households, tenure (own/rent) and even group quarters.
2020 Block Data files – the Demographic and Housing Characteristics (DHC) is released down to the Block level. You can get most of the DHC variables at the block level. There are some exceptions, usually for issues of confidentiality (like single ages by race – those aren’t available until you get to the tract level).
This is the 2020 Census’ most comprehensive data set - giving all of the age breakouts as opposed to the Redistricting’s more minimal age break of under/over age 18 (voting cut off).
The DHC 2020 data is comprised of 5 data sets. There are Population and Housing variables that are available at EVERY geography. Then there are Population and Housing variables that are only available at the Tract level and larger geographies (all geographies except Blocks and Block Groups). And then a small number of variables that are only available at the County level.
